(FILES) Picture of Venezuelan President

CARACAS, VENEZUELA: (FILES) Picture of Venezuelan President Hugo Chavez taken in Caracas, 13 February 2004. Mexican authorities accused Venezuela 15 November 2005 of becoming a major new transit point for illegal heroin trafficking, heightening a war of words after the withdrawal of their ambassadors. Venezuela angrily rejected Mexico's demand that it apologize for statements by Chavez, who has called the Mexican president "a lapdog" of the United States. The row started after Fox criticized Chavez's stance at last week's Summit of the Americas in Argentina. AFP PHOTO/Andrew ALVAREZ (Photo credit should read ANDREW ALVAREZ/AFP via Getty Images)
